  • The window of X Factor opportunity opens up in the closing seconds of a race-you might be sprinting at the time or just hanging one, trying to get across the finish line. With a supreme act of will, you can prolong your effort, essentially fighting off the inevitable lactic acid shutdown. You'll have little time for contemplating the options: either wholeheartedly go for it, or back off. You must train your X Factor to unequivocally respond the way you want-go for it. Once the window is closed, it's closed forever.
